This unit will be a FINAL sale. Meaning, if you do not like the unit, you CANNOT return it. The only warranty we will give it is if you have an out of box failure within the first 14 days. This means that if the unit does not function to manufacturer specifications within the first 14 days, we will replace it. Anything else like noise, weight, oxygen output, etc. will not be considered a valid reason to return the unit.
